mode•Check that the power cable is plugged in and that the power button on the projector cabinet or the remote
control is on. See pages 28 and 30.
•Ensure that the lamp cover is installed correctly. See page 108.
•Check to see if the projector has overheated or the lamp usage exceeds 2100 hours (up to 3100 hours : Eco
mode). If there is insufficient ventilation around the projector or if the room where you’re presenting is par-
ticularly warm, move the projector to a cooler location.
•The lamp may fail to light. Wait a full minute and then turn on the power again.
•The lamp has reached the end of its usable life. Replace the lamp.
•Ensure that the Power Management is off. See page 95.
•Use the SOURCE button on the projector cabinet or the VIDEO, the S-VIDEO, the COMPONENT, the COM-
PUTER 1/2 or the VIEWER button on the remote control to select your source (Computer 1/2, Component,
Video, S-Video or Viewer). See page 32.
•Ensure your cables are connected properly.
•Use menus to adjust the brightness and contrast. See page 78.
•Remove the lens cap.
•Reset the settings or adjustments to factory preset levels using the Reset in the Menu. See page 101.
•Enter your registered keyword if the Security function is enabled. See page 49.
•When using with a notebook PC, be sure to connect between the projector and the notebook PC before turning
on the power to the notebook PC. In most cases signal cannot be output from RGB output unless the notebook
PC is turned on after connecting with the projector.
*If the screen goes blank while using your remote control, it may be the result of the computers screen-
saver or power management software.
*If you accidentally hit the POWER button on the remote control, wait 60 seconds and then press the POWER
button again to resume.
•See also the next page.
•When one of the following happens, the Lamp mode automatically changes from Normal to Eco.
*When there are no signals (blue or black screen) → To return to the Normal mode, select another available
source.
*When the image is muted using the PIC-MUTE button on the remote control → Press the PIC-MUTE button
again to return to the Normal mode.
*When the room where you re presenting is particularly warm → Move the projector to a cooler location.
•Check if an appropriate color is selected in Wall Color. If so, select an appropriate option. See page 80.
•Adjust Hue in Picture. See page 78.
•Reposition the projector to improve its angle to the screen. See page 33.
•Use the 3DReform function to correct the trapezoid distortion. See page 35.
•Adjust the focus. See page 34.
•Reposition the projector to improve its angle to the screen. See page 33.
•Ensure that the distance between the projector and screen is within the adjustment range of the lens. See page
22.
•Condensation may form on the lens if the projector is cold, brought into a warm place and is then turned on.
Should this happen, let the projector stand until there is no condensation on the lens.
•Use the SOURCE button on the projector cabinet or the VIDEO, the S-VIDEO, the COMPONENT, the COM-
PUTER 1/2 or the VIEWER button on the remote control to select your source (Video, S-Video, Component,
Computer or Viewer). See page 32.
•Adjust the computer image manually with the Pixel Adjust/Position in the Image. See page 84.
•Install new batteries. See page 19.
•Make sure there are no obstacles between you and the projector.
•Stand within 22 feet (7 m) of the projector. See page 19.
•Check if one or more remote sensors are enabled. Select [Setup] → [Page 4] → [Remote Sensor] from the
menu. See page 97.
•Make sure that you are in the Projector mode and the PJ button lights in red. If not, press the PJ button. See
page 40.
•See the POWER/STATUS/LAMP Indicator on page 111.
•Press the AUTO ADJUST button on the projector cabinet or the AUTO ADJ. button on the remote control. See

If there is no picture, or the picture is not displayed correctly.
• Power on process for the projector and the PC.
Be sure to connect the RGB cable between the projector and the computer before turning on the computer.
There are some notebook PCs, which do not output signal unless there is \
a projectors or monitor connected
first.
NOTE: Y ou can check the horizontal frequency of the current signal in the proje\
ctor ’s  menu under ‘Menu → Help → Infor ma-
tion.  If it r eads “0kHz”, this means there is no signal being output fr om the computer. See page 100 or go to next step.
•Enabling the computer’s external display.
Displaying an image on the notebook PC’s screen does not necessarily mean it outputs a signal to the projec-
tor.  When using a PC compatible laptop, a combination of function keys will enable/disable the external display.
Usually, the combination of the ‘Fn” key along with one of the 12 function keys gets the external display to come
on or of f.   F or  exampl e, laptops use Fn + F3, while Dell laptops use Fn + F8  ke y combinations to toggle
through external display selections.
• Non-standard signal output from the computer
If the output signal from a notebook PC is not an industry standard, the\
 projected image may not be displayed
correctly. Should this happen, deactivate the notebook PC’s LCD screen when the projector display is in use.
Each notebook PC has a different way of deactivate/reactivate the local LCD screens as described in the
previous step. Refer to your computer’s documentation for detailed information.
• Image displayed is incorrect when using a Macintosh
When using a Macintosh with the projector, set the DIPswitch of the Mac adapter (not supplied with the projec-
tor) according to your resolution. After setting, restart your Macintosh for the changes to take affect.
For setting display modes other than those supported by your Macintosh and the projector, changing the DIP
switch on a Mac adapter may bounce an image slightly or may display noth\
ing. Should this happen, set the DIP
s witch to the 13” fixed mode and then restart your Macintosh. After that, restore the DIP switches to a
displayable mode and then restart the Macintosh again.
NOTE: A Video Adapter cable manufactured by Apple Computer is needed for\
 a PowerBook which does not have a mini D-Sub
15-pin connector .
•Mirroring on a PowerBook
* When using the projector with a Macintosh PowerBook, output may not be s\
et to 1024 x 768 unless “mirror-
ing” is off on your PowerBook. Refer to owner’s manual supplied with your Macintosh computer for mirroring.
• Folders or icons are hidden on the Macintosh screen
Folders or icons may not be seen on the screen. Should this happen, select [View] ->[Arrange] from the Apple
menu and arrange icons.
